To my understanding join --reference doesn't do anything useful in a 2a format tree anyway. It works, but all files in the joined subtree are reported as unknown, including its .bzr directory. That's certainly not the intended behavior, is it?

What is the current state of join --reference? Is it supposed to work at all? And if so, what tree format is required?

No, join by reference doesn't work properly yet. The development-subtree
format does support nested trees but it only allows you to record them.

by-reference nested trees are not supported yet, which is also why "bzr
join --reference" is not shown by e.g. "bzr help join".
